We divide 196928 by 91
The aim is to understand the frequency of 91 in 196928.

Going ahead to step 1:
If we divide 1 by 91, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 91

Moving on to step 2:
The number 91 fits into 19 0 times, leaving a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 19 to get 19.
Append the next digit (6) from the dividend to 19 and continue with: 196 / 91

Advancing to step 3:
91 can be fit into 196 2 times, resulting in a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 14 after subtracting 182 from 196.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 91

Let's proceed to step 4:
91 can be fit into 149 1 times, resulting in a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we subtract 91 from 149, we get 58.
Grab the next digit (2) from the dividend, add it to 58, then carry on: 582 / 91

Let's proceed to step 5:
91 can be fit into 582 6 times, resulting in a remainder of 36.
Record the quotient 6 as the next digit in the result. 
Result so far: 216.0
Deduct 546 from 582 and we're left with 36.
Append the next digit (8) from the dividend to 36 and continue with: 368 / 91

Step 6:
If we divide 368 by 91, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 2164.0
Deduct 364 from 368 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
When dividing 40 by 91, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2164.0
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 8:
91 goes into 400 4 times with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 2164.04
The remainder is 36 after subtracting 364 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
If we divide 360 by 91, we get 3 and a remainder of 87.
Put 3 as the next digit of the answer. 
Result so far: 2164.043
If we take 273 away from 360, we end up with 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Going ahead to step 10:
870 divided by 91 is 9 with a remainder of 51.
Put 9 as the next digit of the answer. 
Result so far: 2164.0439
Deduct 819 from 870 and we're left with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 11:
91 can be fit into 510 5 times, resulting in a remainder of 55.
Write down 5 as next digit of the result. 
Result so far: 2164.04395
Subtract 455 from 510 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 12:
91 goes into 550 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 2164.043956
Subtract 546 from 550 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
40 divided by 91 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 2164.043956
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
400 divided by 91 is 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 2164.04395604
Subtract 364 from 400 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final result is 2164.04395604 with a remainder of 3.6e-08.
